A nurse is caring for a client who underwent a total laryngectomy 1 week ago for laryngeal cancer. Which nursing intervention is most important to prevent respiratory complications?

## 보기

1. Encourage the client to cough and deep breathe every 2 hours
2. Suction the tracheostomy tube as needed to maintain airway patency **✔ 정답**
3. Position the client in semi-Fowler's position at all times
4. Administer humidified oxygen via tracheostomy collar continuously

**정답: 2**

## 해설

Suctioning the tracheostomy tube as needed is critical to prevent airway obstruction from secretions, the most immediate respiratory threat. Other interventions (coughing, positioning, humidified oxygen) are supportive but do not directly remove obstructive secretions.

Understanding the Post-Laryngectomy Airway

A total laryngectomy permanently separates the upper airway (nose, mouth, pharynx) from the lower airway (trachea, lungs). The client now breathes exclusively through a tracheostoma, a surgical opening at the base of the neck. This anatomical change means the natural humidification, warming, and filtering functions of the upper airway are completely bypassed. The most immediate and critical nursing priority is maintaining a patent airway, as any obstruction from secretions can rapidly lead to life-threatening hypoxia.

Analyzing the Options

Let's examine each intervention in the context of this specific surgical alteration.

**Option 1: Encourage the client to cough and deep breathe every 2 hours.**

While coughing and deep breathing are foundational for preventing atelectasis and pneumonia in most postoperative patients, this technique is ineffective for a client with a total laryngectomy. The client can no longer generate a forceful cough through a closed glottis because the trachea no longer connects to the pharynx. Air cannot be pressurized against a closed upper airway. Instead, the client must be taught the "laryngectomy cough" or "tracheal cough," which involves taking a deep breath through the stoma and performing a short, forceful exhalation. Standard coughing instructions are not applicable here.

**Option 2: Suction the tracheostomy tube as needed to maintain airway patency.**

This is the most important intervention. After a laryngectomy, the tracheobronchial tree produces increased secretions due to inflammation and the loss of the mucociliary clearance mechanism's normal humidity. These thick secretions can easily obstruct the tracheostomy tube, which is the client's sole airway. Evidence confirms that secretion management is a cornerstone of preventing postoperative tracheostomy complications, with airway obstruction from mucus plugging being a primary risk [1]. A retrospective analysis of post-laryngectomy complications further identifies pulmonary and airway-related events as significant early complications, reinforcing the need for vigilant airway clearance [2]. The nurse must assess for signs of airway obstruction (e.g., restlessness, increased respiratory rate, decreased oxygen saturation, audible rhonchi) and suction promptly using sterile technique to prevent hypoxia and infection.

**Option 3: Position the client in semi-Fowler's position at all times.**

Semi-Fowler's position (head of bed elevated 30 to 45 degrees) is beneficial for promoting lung expansion and reducing edema. However, it is a supportive measure, not the most critical one. A patent airway takes absolute priority. Furthermore, the instruction to maintain this position "at all times" is not clinically appropriate, as position changes are necessary to mobilize secretions and prevent skin breakdown. The scoping review on intrahospital transport highlights that changes in positioning, especially during transport, can precipitate airway compromise, making direct airway management skills like suctioning even more crucial than a static positioning order .

**Option 4: Administer humidified oxygen via tracheostomy collar continuously.**

Providing humidified oxygen is an essential intervention to compensate for the bypassed upper airway and to help thin secretions, making them easier to clear. However, it is an adjunct to the primary task of keeping the airway clear. If the tracheostomy tube is occluded by a mucus plug, humidified oxygen cannot reach the lungs, rendering the intervention useless. The priority is to first ensure the airway is patent through suctioning; then, humidified oxygen can effectively support gas exchange and secretion management.

Why Airway Patency is the Priority

The nursing process dictates that airway management is the highest priority in any client, based on the ABC (Airway, Breathing, Circulation) framework. For the post-laryngectomy client, the tracheostomy tube is the only airway, making its patency a non-negotiable, life-sustaining requirement. The synthesized evidence for managing postoperative tracheostomy complications strongly emphasizes structured airway care protocols, with suctioning being a key component to prevent obstruction [1]. While all listed interventions are part of comprehensive care, only suctioning directly addresses the immediate threat of airway loss. The high incidence of early postoperative complications in this population, particularly those related to the respiratory system, underscores why direct airway maintenance is the nurse's most critical responsibility [2].References (research sources)

## 임상 시나리오

Post-Laryngectomy Airway ManagementPreventing Respiratory Complications
The highest priority is maintaining airway patency via tracheostomy suctioning. After a total laryngectomy, the upper airway is bypassed, and the client cannot perform a standard cough. Secretions directly obstruct the tracheostoma, leading to rapid hypoxia.

Suctioning should be performed as needed based on assessment (visible secretions, audible gurgling, increased respiratory rate, decreased oxygen saturation). Pre-oxygenate with 100% O2 before and after suctioning.

CautionNever encourage a standard "cough and deep breathe" routine. Instead, teach the laryngectomy cough: a deep breath through the stoma followed by a short, forceful exhalation. Humidification is critical to thin secretions, but suctioning takes precedence when obstruction is present.

## 핵심 개념

- **Total Laryngectomy** — Surgical removal of the larynx, permanently separating the upper and lower airways; the patient breathes solely through a tracheostoma.
- **Tracheostoma** — A permanent surgical opening created at the base of the neck to serve as the sole airway after total laryngectomy.
- **Laryngectomy Cough** — A technique where the patient inhales deeply through the stoma and forcefully exhales, replacing the ineffective standard cough due to the absent glottis.
- **Airway Patency** — The state of the airway being open and unblocked, which is the highest priority nursing intervention to prevent life-threatening hypoxia.
